Not sure of strain. Son’s bag seed origin.
It’s at the 4 or 5th week of flowering with no change in the yellowing of leaves. First yellowing of veins and the the leaves themselves.
Problems: I transitioned over to blossoming booster at first week of flowering. Too soon.
The pot is probably way too small for its size but too late to transfer. Thus it’s most likely root bound.
Last week i gave it a 1/2 dose of Fox Farm grow big along with some Easy Weed seaweed but no change so far with newer growth.
My thoughts are to add some epsom salts and Peroxide to my next watering.
Strickly rain water for moisture and PH seems fine according to inexpensive moisture/light/PH probe.
I was concerned about overwatering but doesn’t follow all symptoms.
I’d appreciate your incite, many thanks. Below some images.
